The occurrence of 5-Iodo-1-(triisopropylsilyl)-1H-pyrrolo[2,3-b]pyridine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Iodo-1-(triisopropylsilyl)-1H-pyrrolo[2,3-b]pyridine (CAS 913983-21-8), a certified reference material (molecular formula C16H25IN2Si, MW 400.37 g/mol) for analytical method development and quality control.
Based on its molecular formula C16H25IN2Si, 5-Iodo-1-(triisopropylsilyl)-1H-pyrrolo[2,3-b]pyridine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 400.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
